EP53A7HQI Datasheet, PDF (16/19 Pages) Altera Corporation – 1A PowerSoC Light Load Mode Buck Regulator with Integrated Inductor

bypass can be placed at the load as long as
there is sufficient separation between the V_OUT
Sense point and the bulk capacitance. The
separation provides an inductance that isolates
the control loop from the bulk capacitance.
NOTE: Excess total capacitance on the output
(Output Filter + Bulk) can cause an over-
current condition at startup. Refer to the
EP53A7LQI/EP53A7HQI
section on Soft-Start for the maximum total
capacitance on the output.
NOTE: The Input and Output capacitors must
use a X5R or X7R or equivalent dielectric
formulation. Y5V or equivalent dielectric
formulations lose capacitance with frequency,
bias, and temperature and are not suitable for
switch-mode DC-DC converter filter applications.
